To learn more about each layer of the atmosphere, click the images below. Thats almost as wide as Earth itself. Due to the lack of vertical convection in the stratosphere, materials that get into the stratosphere can stay there for long times. The ozone layer absorbs the majority of these rays, shielding life from harmful radiation. Providing an environment conducive to good instruction and motivation in which there is an atmosphere of self-motivation and self-discipline in the areas of personal development, character, and academic integrity. 26. Planes fly in the stratosphere to avoid turbulence and fly longer distances using less fuel. However, as you enter the stratosphere, the ozone gas absorbs the ultraviolet light entering the atmosphere from the sun. It is the only layer of the atmosphere where temperature inversion occurs. That trend of rising temperatures with altitude means that air in the stratosphere lacks the turbulence and updrafts of the troposphere beneath. Exosphere widely contains particles of helium and hydrogen. stratosphere, layer of Earth's atmosphere lying between the troposphere and the mesosphere. Due to the high speed of the meteor, it generates a lot of heat resulting from high friction between the particles and the meteor. These distances vary slightly due to elevation changes on the Earth. It also allows the airplane to stay above the turbulent weather of the troposphere. As a result of the EUs General Data Protection Regulation (GDPR). Louise Fisher has taught middle school students introductory physics topics for two years. In fact it is not easy to distinguish between space and not space because of the fact that the Earths atmosphere doesnt simply vanish; rather, it gradually becomes thinner and thinner over about 600 miles. In this region, the temperature increases with height. Its about 6,200 miles (10,000 kilometers) thick. The height of the bottom of the stratosphere varies with latitude and with the seasons. The stratosphere has many defining features that make it a unique part of the atmosphere. The amount of water vapour in the stratosphere is very low, and because of this there are no clouds in the stratosphere. The next layer up is called the stratosphere. During northern hemispheric winters, sudden stratospheric warmings, caused by the absorption of Rossby waves in the stratosphere, can be observed in approximately half of winters when easterly winds develop in the stratosphere. Convection is when gasses cool down as they rise, allowing them to condense onto air particles and form clouds. This breaking is much more pronounced in the winter hemisphere where this region is called the surf zone. However, this feature allows commercial airliners to fly in the lower stratosphere while traveling faster and save fuel. Enrolling in a course lets you earn progress by passing quizzes and exams. The stratosphere is composed primarily of nitrogen and oxygen. 4. Since the stratosphere has increasing temperature with elevation, convection is very rare. 19. However, exceptionally energetic convection processes, such as volcanic eruption columns and overshooting tops in severe supercell thunderstorms, may carry convection into the stratosphere on a very local and temporary basis. Ice clouds form in this layer which is visible when lighted from beneath during sunset. 18. The stratosphere can be as deep 20 miles or as shallow as 5.5 miles. I feel like its a lifeline. All rights reserved. Stated another way, it allows the airliner to fly faster while maintaining lift equal to the weight of the plane. Within no time, the vapor from the exhaust freezes and turns visible. We now know that there are additional ozone loss mechanisms and that these mechanisms are catalytic meaning that a small amount of the catalyst can destroy a great number of ozone molecules. It helps in propagation of the radio waves used in telecommunication. It is the only atmospheric layer where temperature inversion occurs and the region where the ozone layer is situated. The burning of fossil fuels discharges carbon dioxide, while agricultural developments deposit a lot of methane and nitrogen oxides into the atmosphere. In the stratosphere - 'strato' means layer and sphere is the shape of the earth. Ozone molecules in this layer absorb high-energy ultraviolet (UV) light from the Sun, converting the UV energy into heat. If you were to climb a mountain in the stratosphere you would have to take off your warm clothes as you got closer to the top rather than putting them on like we usually do. Clouds form due to convection, which is uncommon in the stratosphere. Earth's atmosphere has six layers: the troposphere, the stratosphere, the mesosphere, the thermosphere, the ionosphere, and the exosphere. Biosphere forms part of the troposphere where life exists. Acidic rains destroy plants and animals, and if it reaches rivers and lakes, it destroys all the aquatic life. They shoot upwards through the stratosphere in a blue column to altitudes as high as 50km! The stratosphere (/strtsfr, -to-/) is the second layer of the atmosphere of the Earth, located above the troposphere and below the mesosphere. The stratosphere is one of the 5 layers of the atmosphere, situated above the troposphere and below the mesosphere at an altitude of 10 km (6 miles), extending to 50 km (30 miles). There are forms of biological bacteria living in the stratosphere. She currently works as a physicist assistant at a cancer treatment center. if(typeof ez_ad_units != 'undefined'){ez_ad_units.push([[300,250],'ownyourweather_com-large-billboard-2','ezslot_3',116,'0','0'])};__ez_fad_position('div-gpt-ad-ownyourweather_com-large-billboard-2-0');if(typeof ez_ad_units != 'undefined'){ez_ad_units.push([[300,250],'ownyourweather_com-large-billboard-2','ezslot_4',116,'0','1'])};__ez_fad_position('div-gpt-ad-ownyourweather_com-large-billboard-2-0_1');if(typeof ez_ad_units != 'undefined'){ez_ad_units.push([[300,250],'ownyourweather_com-large-billboard-2','ezslot_5',116,'0','2'])};__ez_fad_position('div-gpt-ad-ownyourweather_com-large-billboard-2-0_2');if(typeof ez_ad_units != 'undefined'){ez_ad_units.push([[300,250],'ownyourweather_com-large-billboard-2','ezslot_6',116,'0','3'])};__ez_fad_position('div-gpt-ad-ownyourweather_com-large-billboard-2-0_3'); .large-billboard-2-multi-116{border:none !important;display:block !important;float:none !important;line-height:0px;margin-bottom:3px !important;margin-left:auto !important;margin-right:auto !important;margin-top:3px !important;max-width:100% !important;min-height:250px;min-width:300px;padding:0;text-align:center !important;}Recent Posts, Copyright 2023 by Own Your Weather. Planes that are low on fuel also fly at this altitude because they can cover more distance than in the troposphere while using less fuel and encountering less turbulence. This material is based upon work supported by the National Center for Atmospheric Research, a major facility sponsored by the National Science Foundation and managed by the University Corporation for Atmospheric Research. Different definitions place the top of the exosphere somewhere between 100,000 km (62,000 miles) and 190,000 km (120,000 miles) above the surface of Earth. The troposphere, the lowest layer, is right below the stratosphere. 3090 Center Green Drive, Boulder, CO 80301, Air pressure drops, and temperatures get colder, as you climb higher in the troposphere, ACOM | Atmospheric Chemistry Observations & Modeling, CISL | Computational & Information Systems, EdEC | Education, Engagement & Early-Career Development, Government Relations & External Engagement. The water exists in the form of vapor and invisible to plain eyes. Damage to the ozone layer of the stratosphere occurs naturally when volcanic gases and dust reach the stratosphere, but people have been contributing to this as well with the use of aerosol's containing CFCs. Certain birds will even fly in the stratosphere, including swans, cranes, and vultures! 24. It is located just above the troposphere, which is the first layer of the atmosphere closest to the ground. The stratosphere the atmosphere's second layer, and is located right above the troposphere and right below the mesosphere. Commercial airliners typically cruise at altitudes of 912km (30,00039,000ft) which is in the lower reaches of the stratosphere in temperate latitudes. Earth's atmosphere is a jacket of gases that surrounds our planet. The top of the stratosphere is called the stratopause, above which the temperature decreases with height. As a result, air circulation is not as prevalent in this layer of the atmosphere, making it difficult for some gasses to escape. Due to the characteristics of the stratosphere, it is a very important part of Earth's atmosphere. Unlike the troposphere, the stratosphere actually gets warmer the higher you go! The ozone layer is within the stratosphere, which protect the Earth from harmful radiation emitted by the sun. The ozone layer lies in the stratosphere, which absorb the majority of harmful UV radiation from the sun. 3090 Center Green Drive, Boulder, CO 80301, Virtual Ballooning to Explore the Atmosphere, ACOM | Atmospheric Chemistry Observations & Modeling, CISL | Computational & Information Systems, EdEC | Education, Engagement & Early-Career Development, Government Relations & External Engagement. The first is due to the reaction of hydroxyl radicals (OH) with ozone. [2][3] The stratosphere is an atmospheric layer composed of stratified temperature layers, with the warm layers of air high in the sky and the cool layers of air in the low sky, close to the planetary surface of the Earth. Weather balloons also rise up to this level of the atmosphere to collect data without interference of storm clouds. The mesosphere is the third layer of the atmosphere (above the troposphere and stratosphere.) The rising air is literally freeze dried; the stratosphere is a very dry place. We take a closer look at the stratosphere and its defining characteristics. Certain bird species like the common crane, whooper swan, and the Rppel's griffon vulture are capable of flying in the lower stratosphere. 21. The atmospheric gases must retain the heat in the sun rays and reflect them to the earth to keep it warm. 10. Temperature decreases with height throughout the mesosphere. #1. Most airplanes or jets travel in the lower part of the stratosphere. Facts About The Exosphere: The Outermost Layer Of The Atmosphere. In 1985, they observed a hole in the ozone layer above the Antarctic. 35. The next higher layer above the stratosphere is the mesosphere. The stratosphere begins at around 10 kilometers above the surface of the earth. The stratosphere extends from the top of the troposphere to about 50 km (31 miles) above the ground. Without the stratosphere, life on Earth would be much different, if not non-existent. Starting at ground level, it extends upward to about 10 km (6.2 miles or about 33,000 feet) above sea level. It is the highest layer. 17. All air entering the stratosphere must pass through the tropopause, the temperature minimum that divides the troposphere and stratosphere. This site is owned and operated by Autumn Skies Online Pty Ltd, a limited liability company headquartered in Somerset West, South Africa. In fact, the air in the exosphere is constantly - though very gradually - "leaking" out of Earth's atmosphere into outer space. It starts to glow, and the rocks begin to fly off. Polar stratospheric clouds (PSCs) are the exception. It occurs naturally in small (trace) amounts in the upper atmosphere (the stratosphere). PSCs are also called nacreous clouds. Thislayerseparates the rest of the atmosphere from outer space. As you rise through the troposphere, the temperature decreases to around -60 degrees Fahrenheit. The exosphere is the very edge of our atmosphere. [20], Some bird species have been reported to fly at the upper levels of the troposphere. It comprises the magnetosphere and ionosphere. These free-moving elements continuously escape into space due to ballistic trajectories. 25. The stratosphere is actually crucial to allowing us to live on earth, because within the stratosphere you will find the ozone layer. Ozone is a chemical compound consisting of three oxygen atoms. Because of this temperature stratification, there is little convection and mixing in the stratosphere, so the layers of air there are quite stable. The stratosphere is a layer of Earth's atmosphere. They are a combination of supercooled water and nitric acid that develop at very low temperatures. This layer is 22 miles (35 kilometers) thick. Folland. It is the reason why the sky appears blue. The temperatures decrease by 6.5 degrees Celsius each kilometer, reaching -55 degrees Celsius at the top limit of the troposphere, commonly known as the tropopause. 6. The main gases are nitrogen and oxygen, which make up 99% of the atmosphere. At the top of the stratosphere, the density of the air is close to zero. 32. Create your account. Ozone is a blue pungent-smelling gas that helps to absorb the ultraviolet radiation in the sun rays. Earth's atmosphere has a series of layers, each with its own specific traits. This includes the troposphere, mesosphere, thermosphere, exosphere, and stratosphere. The stratosphere is a layer of Earths atmosphere. Autumn Skies Online Pty Ltd is compensated for referring traffic and business to these companies., The Earth's atmosphere consists of five layers. This layer of our atmosphere has its own set of layers. While the troposphere is filled with a vast assortment of clouds thanks to a gas we know as water vapor, the stratosphere is a vast, clear blue sky. This decrease in temperature with altitude is what causes convection to occur in the troposphere. We live in the troposphere, which is the layer of the atmosphere closest to earth. The presence of moisture in the atmosphere is Its like a teacher waved a magic wand and did the work for me. What are the characteristics of the five layers of the atmosphere? Earths atmosphere has six different layers. That's almost as wide as Earth itself. Sydney Chapman gave a correct description of the source of stratospheric ozone and its ability to generate heat within the stratosphere;[citation needed] he also wrote that ozone may be destroyed by reacting with atomic oxygen, making two molecules of molecular oxygen. It contains 80% of the atmospheric weight, making it the densest layer. Its magnetic field goes up to 60,000 km into space. There are no storms or turbulence here to mix up the air, so cold, heavy air is at the bottom and warm, light air is at the top. Some researchers and even students have sent helium balloons with cameras to record the stratosphere. The air in the stratosphere is extremely thin, which makes it impossible to breathe at this level. It changes sometimes unpredictably The stratosphere is where youll find the very important ozone layer. The stratosphere also traps certain gasses known as CFC's, which are chemicals derived from aerosol. Earth is a great planet to live on because it has a wonderful atmosphere around it. Troposphere is the thinnest and closest layer to the earths surface. The atmosphere is dense near the surface of the Earth and protects life on the planet Earth. It extends above the tropopause to an altitude of 50 km above the earth. It means temperatures rise as altitude increases in this region, unlike the other four layers, which are characterized by a drop in temperature as altitude increases. Most of the clouds form in the troposphere, just below the stratosphere. Geomagnetic solar storms caused by solar flares or solar winds can disrupt activities in the ionosphere, causing difficulty in transmitting radio signals and global positioning system signals. Ionosphere plays a vital role in radio signals broadcast on the earths surface. Other gases such as carbon dioxide, argon, helium, and neon occupy the remaining portion. The troposphere is where we breath in and is also referred to as the lower atmosphere. [7] Molecular oxygen absorbs high energy sunlight in the UV-C region, at wavelengths shorter than about 240nm. Stratospheric circulation is a predominantly wave-driven circulation in that the tropical upwelling is induced by the wave force by the westward propagating Rossby waves, in a phenomenon called Rossby-wave pumping. This part of the atmosphere is the most dense. The importance of the stratosphere is highlighted by the presence of the ozone layer, without which no life on Earth will be possible. Ozone, an unusual type of oxygen molecule that is relatively abundant in the stratosphere, heats this layer as it absorbs energy from incoming ultraviolet radiation from the Sun. One wild characteristic of the stratosphere is a phenomenon that occurs, which is known as blue jets. The stratosphere extends from the tropopause at about 10 to 17 km (about 6 to 11 miles) altitude to its upper boundary (the stratopause) at . Stratosphere is the second layer. The atmosphere is about 500 km thick, with a mix of more than ten different gases. Around the poles, it actually begins at around 7 kilometers, whereas around the equator it can be as high as 20 kilometers. 3 It borders the stratosphere below through a thin transitional space called the stratopause. Air pollution causes the demolition of the ozone belt, and without it, the earth would be exposed to the deadly ultraviolet rays in the sun. The coldest temperatures are found in the mesopause. As a result, it tends to trap any and all gases that enter this region of the atmosphere. The atmosphere comprises five layers: troposphere, stratosphere, mesosphere, thermosphere and exosphere. [22][23], In 1902, Lon Teisserenc de Bort from France and Richard Assmann from Germany, in separate but coordinated publications and following years of observations, published the discovery of an isothermal layer at around 1114km, which is the base of the lower stratosphere. The stratosphere is a layer of extremely stratified air that rises 40 kilometres above the tropopause and comprises about 20% of the atmosphere's mass. Commercial passenger jets fly in the lower stratosphere, partly because this less-turbulent layer provides a smoother ride. These events often precede unusual winter weather [16] and may even be responsible for the cold European winters of the 1960s.[17]. Never miss out again when another interesting and helpful article is released and stay updated, while also receiving helpful tips & information by simplyclicking on this link .Until next time, keep your eye on the weather! - There are no clouds in the layer, and though . It is enough to cover the entire earths surface with 1 cm of rain. 4 The mesosphere is a layer of Earth's atmosphere. The HO2 radical produced by the reaction of OH with O3 is recycled to OH by reaction with oxygen atoms or ozone. The Stratosphere also has three thrill rides at the top. This increase of temperature with altitude is characteristic of the stratosphere; its resistance to vertical mixing means that it is stratified. That means that to get to outer space, you have to be really far from Earth. The destruction of the ozone layer lets an enormous amount of ultraviolet rays reach the earth, which leads to skin cancer and cataracts in humans and animals alike. It is the only atmospheric layer where temperature inversion takes place. Moreover, it regulates the temperature extremes that are likely to occur between day and night. The atmosphere surrounds our planet like the peel of an orange. Strat means layer. [19] In 2001, dust was collected at a height of 41 kilometres in a high-altitude balloon experiment and was found to contain bacterial material when examined later in the laboratory. Variations in the amount of energy coming from the Sun exert a powerful influence on both the height of the top of this layer and the temperature within it. Near the equator, the lower edge of the stratosphere is as high as 20km (66,000ft; 12mi), at midlatitudes around 10km (33,000ft; 6.2mi), and at the poles about 7km (23,000ft; 4.3mi). The resultant breaking causes large-scale mixing of air and other trace gases throughout the midlatitude surf zone. The lack of particles in the air causes less friction to hold an aircraft back, which requires less power to travel faster and further. Skin cancer frequency is increasing due to the thinning of the ozone layer. The aurora, the Northern Lights and Southern Lights, occur in the thermosphere. Three Highest Thrill Rides in the World. Like the other atmospheric layers, it does not have a fixed height but starts at an altitude of approximately 10 km(6 miles), extending up to a height of roughly 50 km(30 miles). Nitrous oxide (N2O) is produced by biological activity at the surface and is oxidised to NO in the stratosphere; the so-called NOx radical cycles also deplete stratospheric ozone. The temperatures in the ozone belt are higher than in the troposphere since the ozone absorbs the ultraviolet rays. Autumn Skies Online Pty Ltd also participates in affiliate programs with Clickbank, CJ, ShareASale, and other sites. Any opinions, findings and conclusions or recommendations expressed in this material do not necessarily reflect the views of the National Science Foundation. The temperatures at the different atmospheric layers differ depending on solar radiation, humidity, and altitude. OH is formed by the reaction of electrically excited oxygen atoms produced by ozone photolysis, with water vapor. The electrically charged atoms and molecules that are formed in this way are called ions, giving the ionosphere its name and endowing this region with some special properties. Air density in this layer gradually decreases as you go higher. Gases and dust from volcanic eruptions often meet the same fate, remaining trapped in the stratosphere for months or even longer. Temperature decreases with height throughout the mesosphere. It is easy & understandable to view our atmosphere as a continuous layer of air. Without the stratosphere, life on Earth would be very different or non-existent, as the shielding of the sun's radiation is important for known Earth life. The following list highlights the characteristics and facts of the stratosphere in more detail. https://en.wikipedia.org/w/index.php?title=Stratosphere&oldid=1140010063, This page was last edited on 18 February 2023, at 00:23. [4] The temperature inversion is in contrast to the troposphere, near the Earth's surface, where temperature decreases with altitude. Ninety-nine percent of the gases that compose the atmosphere are located below a height of 32 km (20 miles). This is how certain gases become trapped in the stratosphere, like CFC's and ozone. The atmosphere comprises five layers: troposphere, stratosphere, mesosphere, thermosphere and exosphere. The atmospheric balance is jeopardized by human activities that cause global warming, greenhouse effect, ozone belt destruction, air contamination, and acid rains. Earth's atmosphere is similar to a jacket for our planet. It acts as a giant sponge and absorbs the vast majority of the sun's dangerous Ultraviolet Light. Certain swans, cranes, and vultures can fly in the lower stratosphere. The stratosphere is the second layer of the atmosphere. When the ozone absorbs ultraviolet radiation, it actually causes another phenomenon that is used to identify different layers in the atmosphere. A two-step reactive mechanism produces ozone in the stratosphere naturally. stratosphere The atmospheric layer above the troposphere, which extends on average from about 10 to 50 km above the Earth's surface. Write CSS OR LESS and hit save. The stratosphere the atmosphere's second layer, and is located right above the troposphere and right below the mesosphere. Composed of mostly nitrogen and oxygen, the stratosphere also contains the ozone layer. They are much similar to warm breath during cold weather. They result from ionized particles from the sun striking the upper atmosphere above the poles. 9. The stratosphere protects Earth life from extremely harmful UV rays from the sun. 29. Most clouds appear here, mainly because 99% of the water vapor in the atmosphere is found in the troposphere. On October 24, 2014, Alan Eustace became the record holder for reaching the altitude record for a manned balloon at 135,890ft (41,419m). So, what does the stratosphere do? 15. 13. This was based on temperature profiles from mostly unmanned and a few manned instrumented balloons. Since almost almost weather activity is limited to the troposphere and almost no water vapor is present in the stratosphere, Polar Stratospheric Clouds is the only visual meteorological phenomenon that can be observed in the stratosphere. He concluded that there was another layer in the atmosphere above the troposphere, which he called the stratosphere. Stratosphere is the second layer. The other four layers include the troposphere, mesosphere, thermosphere, and exosphere. The stratosphere is located above the troposphere and below the mesosphere. 8. Stratosphere - The Stratosphere makes up around 25% of the total of Earth's atmosphere, and is home to more than 90% of our Earth's O-Zone layer. Ionization takes place in the ionosphere caused by the suns radiation. The particles in this layer are electrically charged, and when they hit each other, aurora australis can be observed. It is the second layer of the atmosphere as you go upward. The stratosphere is a region of intense interactions among radiative, dynamical, and chemical processes, in which the horizontal mixing of gaseous components proceeds much more rapidly than does vertical mixing. If you do your calculations, each water vapor particle spends approximately nine days in the atmosphere. This diagram shows some of the features of the stratosphere. The stratosphere is the second layer of the Earth's atmosphere, and lies approximately 10km to 50km above the Earth's surface. The stratosphere is the second layer in the Earth's atmosphere. Since the ozone layer absorbs UV rays from the sun, it heats up, which allows temperatures to increase as altitude increases. (The ozone layer is too large a topic for this article, but you can read more about it in the following post.). It also consists of a layer known as the ozone layer, a blanket of ozone that absorbs harmful ultraviolet (UV) rays from the sun. These elements react with toxic gases, salt, smoke, and volcanic ash. The Earth's atmosphere is a mixture of several gases. In comparison, the warmest in the thermosphere. It is also roughly 35 kilometers (22 miles) thick. Brewer-Dobson Circulation occurs in the stratosphere. Mercury's magnetic field is different at its poles. Requested URL: byjus.com/chemistry/stratosphere/, User-Agent: Mozilla/5.0 (iPhone; CPU iPhone OS 15_5 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/15.5 Mobile/15E148 Safari/604.1. It keeps us warm, gives us oxygen to breathe, and it is where our weather happens. Convection is the process whereby warm air rises and cooler air descends. But there are no mountains high enough to reach the stratosphere, so you dont have to worry about that. Since blue light has short wavelengths, it gets reflected more compared to other colors. The temperatures in the ozone belt are higher than in the troposphere since the ozone absorbs the ultraviolet rays. Certain birds can fly to this altitude, including cranes, swans, and vultures. Airplanes fly in the stratosphere to avoid turbulence. 20. Some of these waves and tides carry energy from the troposphere upward into the stratosphere, others convey energy from the stratosphere up into the mesosphere. Due to this, the stratosphere has very little convection, which causes chemicals derived from aerosols, known as CFC's, to become confined to the stratosphere. The oxygen atom product combines with atmospheric molecular oxygen to reform O3, releasing heat. This results in an increase in temperature from about -76 degrees Fahrenheit to around 5 degrees Fahrenheit. They are far much apart from that they can move thousands of kilometers without colliding. 2. Although some experts consider the thermosphere to be the uppermost layer of our atmosphere, others consider the exosphere to be the actual "final frontier" of Earth's gaseous envelope. On November 29, 1973, a Rppell's vulture (Gyps rueppelli) was ingested into a jet engine 11,278m (37,000ft) above the Ivory Coast. Above the stratosphere is the mesosphere. Just like the troposphere, its depth varies with latitude. The particles in the exosphere do not behave like gases. That's much thicker than the inner layers of the atmosphere, but not nearly as thick as the exosphere. The wind, which is the air current, is generated when the hot air rises and gets replaced by colder air. This is due to gravity, but mostly due to the temperature inversion in the tropopause that prevents gases from entering the layer. The stratosphere extends from from 4 -12 miles (6-20 km) above the Earth's surface to around 31 miles (50 km). Rocket launches inject exhaust gases into the stratosphere, producing uncertain consequences. The stratospheric air is extremely thin and dry since the vast majority of atmospheric gases (and weather activity) are limited to the troposphere. This ozone layer is important for man's survival, and for the survival of life on earth, as it absorbs the UV radiation from the sun that would otherwise be deadly. The thinning is most pronounced in the polar regions, especially over Antarctica. copyright 2003-2023 Study.com. [6], The mechanism describing the formation of the ozone layer was described by British mathematician Sydney Chapman in 1930. The composition of the atmosphere of each celestial body is different. The overall circulation of the stratosphere is termed as Brewer-Dobson circulation, which is a single-celled circulation, spanning from the tropics up to the poles, consisting of the tropical upwelling of air from the tropical troposphere and the extra-tropical downwelling of air. She earned her bachelor's in Physics and Astronomy from the University of North Carolina at Asheville.
